WATCHCASE-PEN DANT.

SPECIFICATION forming part of Letters Patent No. 526,030, datedSeptember 18, 1894. Appnmioinea August so, 189s. serai No. 484.395. (Nomodel.)

To @ZZ whom it may concern,.-

Be it known that I, AeILn N. GAUTHIER, of New Orleans, in the parish ofOrleans and State of Louisiana, have invented certain new andusefulImprovementsin "Watch-Pendants and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it pertains tomake and use it, reference being had to the accompanying drawings, whichform part of this specification.

My invention relates to an improvement in watch pendants; and itconsists in the novel manner of securing therein the bow and thecombined push pin and winding stem, as will be described hereinafter andespecially referred to in the claims.

My invention is directed toward providing a means for holding the bowsecurely in place, and it is further directed toward providingamechanism for holding the winding stem in proper adjustment within thependant, whether the same be moved longitudinally before setting thewatch or remains in its normal position for accomplishing thisoperation.

Referring to the accompanying drawings: Figure 1, is a verticalsectional View of a watch pendant having myimproved mechanism appliedthereto. Fig. 2, is a side elevation of the same, a portion of thewinding cap being shown in section. Fig. 3, is a cross sectional view online 3 3, of Fig.`1. Fig. 4, is a ldetached perspective view of one ofthe springs. Fig. 5, is a detached view of the stem and longitudinalsleeve.

A designates the watch case and B the pendant having the usual bowopenings Bin its opposite sides.

C is the bow having knobs C removably secured to its ends which bear inopenings B. These knobs are held in place by screws c, having keys c',upon their inner ends for the purpose presently to be explained.

D designates semicylindrical plates each having a bayonet slot D. Theseplates are insertible longitudinally in the pendant and their bayonetslots are engaged as shown by the keys c', thereby locking the bowfirmly in place. Dove tail slots E upon opposite sides of the upper endof the pendant are engaged by the correspondingly formed lateralprojections or flanges M upon each of the plates D, and in this mannerthe plates are held firmly within the pendant and against longitudinalmovement.

F is the combined winding stem and push pin having the usual crown F atits outer end, while projecting from its inner end is the angularwinding stem G. Near the lower end of the stem is formed the liangeI-I,while immediately above the same is the annular bulge I. The lowerends of the spring plates D are contracted and flared inward as shown atJ where they rest on the bulgeIof the stern holding the same normallyfrom outward movement.

A longitudinal sleeve K encircles the stem from the crown F to the pointwhere the lower ends of the spring plates D begin'to contract. Thissleeve serves to hold the stem exactly in the center of the pendant andthe plates D pushed outward against the inner wall of the same. Theslots K are formed on opposite sides of the sleeve which take theprojecting ends of the bow, which latter prevent the sleeve from turningin the pendant. These slots permit the ready adjustment and removal ofthe sleeve. The lower end of the stem F rests on the spring catch L,which holds the lid of a hunting case watch closed and the said latch isdepressed for opening the watch by pushing inward the said stem in theusual manner, there being room between the crown F and the pendant B topermit of this movement.

In a stem winding mechanism in which the stem is not moved outward forsetting the hands the relative positions of the spring plates and stemare not changed. In the pendant setting mechanism, or that in which thestem is moved outward longitudinally a pull upon the stem moves thebulge I, outward between the ends .I of the spring plates, so that thelatter rest on the shoulder H. The stem is then in position for settingthe hands.

An inward push` on the stem returns the bulge I between the plate ends.I thus returning the stem to its normal position. It will be seen thatthe respective engagements of the bulge I and shoulder H, with the endsof the spring plates hold the stem firmly in the desired adjustment.

ICO

By the construction and arrangementherein shown and described it isimpossible vfor the bow to become detached from the pendant or the stemto move longitudinally therefrom so long as the spring plates D are inplace, and the latter are so held as to prevent longitudinaldisplacement. are beveled downward at their outer ends as shown at E',so that a screw driver or other implement may be applied beneath the[langes M, and in this way the latter may be readily7 pushed inward anddisengaged from the said slots when the spring plates are to be removed.The removal of the other parts is readily et- 'fected by firstunscrewing the crown from the stem, and then removing the sleeve K,after which the spring plates and stem mayin turn be readily taken out.The removable knobs C take up all wear between the pendant and bow andare readily detached so that new ones may be easily substituted.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

l. The combination of a pendant, a bow, plates, secured within thependant which are in engagement with the bow ends, and a push pin whichis held from outward movement by the said plates, substantially as shownand described.

2. The combination with a pendant having dovetailed grooves on its upperend, curved plates extending in to the pendant, dove tailed llangesprojecting` from the upper ends thereof which fit the correspondinggrooves in the pendant, and a push pin which is held from The bottoms ofthe slots E outward movement by the said plates, substantially as shownand described.

The combination of a pendant having transverse openings adjacent itsupper end, plates extending longitudinally in the pendant, projectionsextending' therefrom which tit the openings in the pendant, and a pushpin held in place by the said plates, substantially as shown anddescribed.

Il. The combination ot a pendant, a bow, longitudinal curved plateswithin the pendant havin g bayonet slots formed therein, projections onthe bow ends which engage the bayonet slots and a push pin held in placeby the said plates, substantially as shown and described.

5. rhe combination of a pendant, curved longitudinal plates securedwithin the pendaut,a push pin engaged and held in place by the innerends of the plates, and a sleeve separating the pin and plates,substantially as shown and described.

t5. The combination with the pendant having openings in its oppositesides, and the bow, of slotted platesl) forthe purpose stated, knobs C,screws c, for securing said knobs in position on the bow ends, and keysc carried by said screws which engage the slots of the plates,substantially as shown and described.
